  • Publicada: 09.04.2026
  • Actualizado: 11.10.2026 10:22

Impact

Multiple Code Paths Missing Base64 Pre-Allocation Size Checks.

Several base64 decode paths could allocate before enforcing decoded-size limits.

OpenClaw is a user-controlled local assistant. This advisory is scoped to the OpenClaw trust model and does not assume a multi-tenant service boundary.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected versions: <=v2026.4.2
  • Patched versions: 2026.4.8

Fix
